Louisa said that she could easily win friends in the house by revealing that she was dating former boyband singer Andy Scott-Lee, but proudly proclaimed that she wasn't prepared to do that.
Speaking to Deana Uppal, Lydia said: "I don't speak about it for a reason. I don't want rent-a-friends.
"What have I said every single time? I'm not talking about it. If I was clever, I would tell them now to buy me some extra friend time. It's old for them now, the celebrity side has now worn off because time has passed. It's now gone back to being bloody vultures."
Lydia also said that she was tired of being friendly with people, commenting: "I can't be arsed. I'll play it to a certain extent. But I'm not going to lose any sleep over it. This is a bloody mess right now. The people with good hearts are getting chopped off."
The dancer also appeared to admit that she was in the show to win it and to find fame.
"I find it so funny when people come on TV and they say I don't want to be famous. It's like, 'Why are you going on TV?' The second thing is 'I don't want to win'. When clearly they do want to win," she said.
